Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621510, here are decompositions:

19 + 33621491 = 33621510
37 + 33621473 = 33621510
73 + 33621437 = 33621510
101 + 33621409 = 33621510
103 + 33621407 = 33621510
113 + 33621397 = 33621510
127 + 33621383 = 33621510
149 + 33621361 = 33621510

Showing the first eight; more decompositions exist.
